Your views on saddle height calculations I used to ride on a version of inside leg X 109 % or less 10cm However, I am getting older, stiffer, and more sedentary. A nagging back pain and groin pains have led me to doubt these formulas. Thus I have reverted to the traditional heel on pedal measure. So far the back pain has gone. I should add that I ve pelvic asymetry ie I have a dominant right side and a left side that's stiff and won't stretch like the right side. I once had a saddle with the left side more depressed than the right. I wonder if any one else has revertred to the heel on pedal measure away from 109% formula. The difference, for me , is significant.
